Health

• Health is not just the outcome of genetic or biological processes• It is also influenced by the social and economic

conditions in which we live. • These influences have become known as the

‘social determinants of health’

Key points-1• Social determinants of health refer to the social,

economic, political, legal and material factors that affect health and cause disease.• Social conditions in which people live powerfully

influence their chances to be healthy. • Factors such as poverty, food insecurity, social

exclusion and discrimination, poor housing, unhealthy early childhood conditions and low occupational status, etc. are important determinants of most diseases, premature deaths and health inequalities between and within countries.

Key points-2• Health is influenced, either positively or negatively,

by a variety of factors. Some of these factors are genetic or biological and are relatively fixed. Social determinants of health arise from the social and economic conditions in which we live and are not so fixed. • The kind of housing and environments we live in, the

health or education services we have access to, the incomes we can generate and the type of work we do, for instance, can all influence our health, and the lifestyle decisions we make.

Main factors A range of factors has been identified to have

influence on the health status of individuals: - From the wider socioeconomic and individual

perspective: inequality; poverty; social exclusion; socio-economic position; income; public policies; health services; employment status; education; housing; transport; the built environment; health behaviours or lifestyles; social and community support networks and stress.- Life course perspective provides a framework for understanding how these social determinants of health shape and influence an individual’s health from birth to old age.

Life course perspective• Life cycle or life course perspective provides a useful

framework for understanding how social determinants influence health and the generation of health inequalities and for identifying entry points for interventions.• Life course perspective, briefly, is the view of life as

an integrated continuum of different stages. • It explores how different social determinants

operate or accumulate as advantages or disadvantages over different stages of the lifecycle.• What happens in different stages of life can affect

health over the entire lifespan.

Health inequality, inequity and social gradient1. Health inequalities refer to differences between individuals,

seen primarily as a consequence of individual biological differences.

2. Health inequity refers to differences in health that are unfair and avoidable, but potentially amenable to change.

3. Social gradient in health refers to differences in health at each step of the social scale within societies; the lower the step, the lower is one’s life expectancy and more common is disease and disability

4. Social determinants contribute to health inequities between social groups. This is beacuse the effects are not distributed equally or fairly accross society.

Multi-causality

A range of factors contribute to health inequalities:• Socio-economic or material factors such as

government social spending and the distribution of income and other resources in society which influence the social and built environment.• Psychosocial factors such as stress, isolation, social

relationships and social support.• Behavioral or lifestyle factors.

Health equity• Health equity is defined as the ‘absence of unfair

and avoidable or remediable differences in health’ among social groups (Solar and Irwin 2007). • Health equity is therefore about the values of

fairness and justice. • A focus on health equity means valuing health as an

essential and valuable resource for human development, helping people reach their potential and contribute positively to society. • Health also represents an important public good, an

investment in human, societal and economic development.

Attention!

While all health inequities are health inequalities, not all health inequalities are health inequities.

Some examples-1

• Baby girls are more likely to have lower birth weights than baby boys.• Poor mothers are more likely to have

lower birth weight infants than non-poor women.• Younger adults are more likely to be

healthier than the elderly.14

Some examples-2

• Poor mothers are more likely to have less prenatal care than non-poor mothers.• Lower immunization rates and higher

malnutrition and mortality among girls in some countries.•Migrant workers have a lower lifespan

than other blue collar workers. 15

Inequity-1

• Inequity is an ethical concept based on justice. • Inequity deals with inequalities that

prevent disadvantaged social groups like the poor; marginalized racial, ethnic or religious groups; women or rural populations living healthy lives.

16

Inequity-2

• In operational terms: It is basically the elimination of “systematic” health inequalities in the base of which lies social disadvantage and marginalization.• Inequity framework focuses on socially

disadvantaged and marginalized groups within and between countries. 17

Disenfranchised groups...

18

Inequity-3

• In order to provide equal opportunities in heath, the determinants of health and manifestations of inequalities should be recognized and noticed.• Therefore, equity in health requires

value-based determination, which should be devoid of simple pragmatic calculations. 19

Basic approaches:1. Focusing on the most disadvantaged groups: This

targets the worst off or poorest groups and aims to improve their health through specific measures. This approach can improve the health of those who are worst off, even if the health gap between rich and poor is unchanged.

2. Narrowing health gaps: This aims to improve the health of those who are poorest or most disadvantaged by raising their health outcomes closer to those who are most advantaged. This usually involves target setting to reduce the disparity in health outcomes between the most advantaged and most disadvantaged groups.

3. Reducing the social gradient: Tackling the social gradient in health involves reducing differences and equalizing health all along the income ladder

Key social determinants of health1. Poverty and Inequality2. Social Exclusion and Discrimination3. Life Course 4. Public Policies and Services5. The Built Environment6. Work and Employment7. Community and Social Participation8. Health Behaviors9. Stress

Poverty

• Poverty is an important risk factor for disease and premature death. • It affects health directly and indirectly, in many ways,

e.g. financial strain, poor housing, poorer living environments and poorer diet, and limited access to employment, other resources, services and opportunities. • Poor health can also cause poverty.

Social exclusion

• Social exclusion is the process by which groups and individuals are prevented from participating fully in society as a result of a range of factors including poverty, unemployment, caring responsibilities, educational background, gender, age, disbility or homelessness.

Discrimination

• Social exclusion is often compounded by discrimination which can arise on the basis of person’s gender, race, ethnicity sexual orientation, religion, etc.

Life course perspective

• The influence of wider social conditions on health is significant at different points of the lifecycle, particularly when people are most dependent or vulnerable, e.g. childhood, pregnancy and older age. • Recent research shows how accumulated social

disadvantage or advantage over the lifecycle influences health and well-being, the likelihood of illness and of premature death. • These influences occur across the life course,

from ‘womb to tomb’

Public policies and services

• Although individuals can make choices in everyday life that may improve and protect their health, they are not completely in control of the social conditions in which they live and work.• Public policy exerts a powerful influence on

these external conditions, and can play an important role in supporting individuals by creating conditions conducive to good health. • Public policy also has an important role to play in

encouraging other sectors to contribute to greater health equity.

Health services

• In the case of both primary care and hospital services, access based on need rather than on the ability to pay is important for health equity. • Comprehensive and equitable primary health

care is vital to supporting healthy lives and to the identification and care of health problems as they arise within the community.• Access to primary health care also has the

potential to reduce the need for more costly acute hospital care in the longer term.

Education

• The foundations for life-long health are set down in childhood. Childhood poverty casts a long shadow over the health of an individual.• Poverty is an underlying determinant of ill health

and education is regarded as a very important route out of poverty. • Research on health inequalities has frequently

shown that those with poorer levels of education experience poorer health.• Education is a strong indicator of a person’s

socio-economic status

Gender

• Gender differences in health and mortality are complex and not yet fully understood. • The social determinants of health have both

similar and different effects on men and women.• Women seem to have a biological advantage

over men in terms of life expectancy.• Men tend to die younger than women, and

research suggests that the work they do and issues like job security and unemployment often affect men’s health.

Policy making

• More equitable and adequately resourced public services contribute to greater social inclusion and a fairer distribution of resources and opportunities in society. • Access to health services should be based on

need rather than on ability to pay.• The opportunity to live in a healthy

neighborhood and to live in decent, warm, affordable housing or accommodation is important for health.
